Overview
Moving from Flash Lead Sales to Twenty CRM requires working around a platform that has no documented public API, which means all data extraction relies on the built-in CSV export feature. Flash Lead Sales records deal stage transitions as activity log entries rather than structured fields, so we extract the full activity export to manually reconstruct stage progression timelines in Twenty. We map unlimited Leads and Contacts from Flash Lead Sales to Twenty's CRM Object (the unified People model), custom pipeline stages to Twenty's Stage configuration, and preserve owner assignments by email resolution. Social message threads export as flat text without thread structure; we attach the full conversation log to the contact record in Twenty. Automations, workflows, and reporting dashboards do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in Twenty's automation framework.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Flash Lead Sales object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Flash Lead Sales
Lead
Twenty CRM
People CRM Object
1:1Flash Lead Sales Leads map directly to Twenty's People CRM Object, which serves as the unified record for prospects and customers. The Lead name, email, phone, location, and custom properties migrate as standard and custom fields on the People record. We preserve the Flash Lead source attribution (Facebook, Instagram, Referral, Purchased List) as a custom text field on the People record, and tags migrate as comma-separated text or to Twenty's Topics if the customer chooses that classification model during scoping.
Flash Lead Sales
Contact
Twenty CRM
People CRM Object
1:1Flash Lead Sales Contacts map to Twenty's People CRM Object, treating Leads and Contacts as a unified record in Twenty's model. The Flash Lead contact's name, email, phone, purchase history, location, and previous conversation references migrate as fields on the People record. We set a source_system__c custom field to 'FlashLead' to identify migrated records. If a Contact already exists as a People record from a prior Lead conversion in Flash Lead, we match on email and update rather than duplicate.
Flash Lead Sales
Lead Stage
Twenty CRM
Opportunity Stage
lossyFlash Lead Sales records stage transitions as activity log entries, not as a structured stage-history table. We extract the full activity log during CSV export, parse stage-change events by timestamp, and reconstruct the progression timeline as a custom stage_history JSON field on the corresponding Opportunity in Twenty. The current stage at migration time maps to the Opportunity's Stage field. Stage-specific probability percentages are mapped from Flash Lead's stage configuration to Twenty's Stage values.
Flash Lead Sales
Deal
Twenty CRM
Opportunity
1:1Flash Lead Sales Deals map to Twenty Opportunities attached to a People CRM Object (the deal contact). We map the deal amount, expected close date, and custom deal fields to their Twenty equivalents. The pipeline assignment from Flash Lead maps to Twenty's Opportunity pipeline configuration. Any deal-specific notes or attachments migrate as comments or file attachments on the Twenty Opportunity.
Flash Lead Sales
Custom Pipeline Stages
Twenty CRM
Opportunity Stage Values
lossyFlash Lead Sales pipeline stages are user-defined with no enforced schema, and one account's stages may not map to another's. We extract the complete stage list during discovery, produce an explicit mapping table assigning each Flash Lead stage to a Twenty stage or creating new ones, and configure stage probabilities in Twenty before migration. Stage-specific automation rules from Flash Lead are documented for manual rebuild in Twenty's automation framework; they do not migrate as code.
Flash Lead Sales
Team Member
Twenty CRM
User
1:1Flash Lead Sales Team Members with role-based access controls map to Twenty User records. We resolve owners by email match during migration. Any Flash Lead Team Member without a matching Twenty User goes to a reconciliation queue for the customer to provision before record import resumes. Role-based visibility from Flash Lead maps to Twenty's workspace-level permissions.
Flash Lead Sales
Tag
Twenty CRM
Custom Text Field or Topic
lossyFlash Lead Sales tags are applied to Leads without limit and serve as segmentation and filtering mechanisms. We export all tags as a comma-separated string on each record. Tags migrate as a custom multi-value text field or to Twenty's Topics with TopicAssignment records, depending on whether the customer wants tag-based filtering as a first-class feature in Twenty. The customer selects the tag strategy during scoping.
Flash Lead Sales
Lead Source
Twenty CRM
Custom Field
1:1Flash Lead Sales Lead Sources (Facebook, Instagram, Referral, Purchased List) track where leads originated and are preserved as a custom text field on the People CRM Object in Twenty. Source labels map directly without transformation. If the customer uses multiple Flash Lead source categories, we preserve the full label as entered in Flash Lead.
Flash Lead Sales
Invoice
Twenty CRM
Opportunity + Custom Fields
1:1Flash Lead Pro invoices tied to Deals migrate as custom fields on the corresponding Twenty Opportunity (invoice amount, invoice status, invoice number). Full invoice formatting and custom invoice fields require field-level mapping per the customer's Flash Lead configuration. Invoice PDFs are attached as files to the Opportunity record. If the customer requires full invoicing functionality in Twenty, they use Twenty's native Opportunity fields or a third-party invoicing integration post-migration.
Flash Lead Sales
Social Message Thread
Twenty CRM
Custom Text Field or File Attachment
1:1Flash Lead Sales Facebook Messenger and Instagram DMs export as flat text logs attached to the contact record without thread structure, timestamps, or read receipts. We attach the full conversation log as a text file to the corresponding People CRM Object in Twenty. We document the limitation in the migration report so the customer can assess whether conversation history is business-critical. Thread metadata (branching, timestamps, read receipts) cannot be reconstructed from the export.
Flash Lead Sales
Automation Rules
Twenty CRM
None (documented for rebuild)
1:1Flash Lead Sales automated workflows for lead assignment, reassignment, and email sequences are stored as configuration rather than data. We do not migrate automation rules. We deliver a written inventory of every active Flash Lead automation with its trigger, conditions, actions, and a recommended Twenty automation equivalent. The customer's admin rebuilds these in Twenty's automation framework post-migration.
Flash Lead Sales
Reports and Dashboards
Twenty CRM
None (documented for rebuild)
1:1Flash Lead Sales reporting dashboards and insights are platform-generated views that cannot be exported as data. We deliver a written summary of the existing Flash Lead report structure (report types, filters, metrics) so the customer can recreate equivalent views in Twenty's reporting module. We do not rebuild reports as part of the migration scope.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Flash Lead Sales gotchas
No documented public API for programmatic export
Lead stage history stored as activity log rather than discrete fields
Custom pipeline stages require explicit mapping per account
Social message threads export as flat text without thread structure
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Discovery and export coordination
We audit the Flash Lead Sales account to document the full object inventory (Leads, Contacts, Deals, Team Members, tags, sources, invoices, social messages), custom pipeline stage names and probabilities, and any automation or reporting configuration requiring documentation. Because Flash Lead Sales has no API, we coordinate with the customer to run the built-in CSV export for all available objects. We verify that the export includes current stage, source attribution, tags, and owner assignment before scoping begins. We identify any objects or fields absent from the export and request supplemental data or activity log downloads.
Twenty workspace preparation and schema configuration
We configure the destination Twenty workspace before any data import. This includes setting up the Opportunity pipeline with stage values mapped from the Flash Lead stage list, creating any custom fields needed to capture Flash Lead properties (lead source, tags, original system indicator), and provisioning User records for each Flash Lead Team Member with matching email addresses. We configure Twenty's API access credentials for the migration user. Schema configuration is validated in Twenty's staging environment before production migration begins.
Stage history reconstruction
We extract the full Flash Lead activity log from the CSV export, parse stage-transition events by timestamp, and reconstruct the chronological stage progression for each deal. We create a custom stage_history JSON field on each Twenty Opportunity containing the sequence of stage transitions (stage name, timestamp, owner at time of transition). This reconstructs the deal velocity and time-in-stage metrics that Flash Lead Sales stores as activity entries rather than discrete fields. The current stage at migration time populates the Opportunity Stage field.
Owner reconciliation and User provisioning
We extract every distinct Flash Lead Team Member referenced on Lead, Contact, Deal, and activity records and match by email against the Twenty workspace's User table. Any Flash Lead Team Member without a matching Twenty User goes to a reconciliation queue for the customer's admin to provision before record import resumes. Owner assignments on migrated records resolve by email match to the provisioned Twenty User.
Production migration in dependency order
We run production migration in record-dependency order: Users (validated), People CRM Object records (Leads and Contacts with source attribution, tags, and original system field), Opportunities (with stage, amount, close date, and reconstructed stage_history), then social message logs as file attachments. Each phase emits a row-count reconciliation report before the next phase begins. We run a final delta check after cutover to capture any records modified in Flash Lead during the migration window.
Cutover, validation, and automation rebuild handoff
We freeze Flash Lead Sales writes during cutover, run a final delta migration, then enable Twenty CRM as the system of record. We deliver the automation and workflow inventory document to the customer's admin team for rebuild in Twenty's automation framework. We do not rebuild Flash Lead automations as Twenty automations inside the migration scope. We support a one-week hypercare window where we resolve reconciliation issues raised by the customer's team.
